Obviously, there's a huge question left here - please Maude tell me that they're not raising the cows *specifically* to butcher them in order to throw 'em into the railroad hopper?? Please tell me that they're only "recycling" the entire animal after they've died of natural causes after a long and happy lifetime of frolicking in the fields producing manure for the train instead? 'Cuz if not - this next sentence is really horrifying:
"It takes about 30 cows to power the train along its 75-mile route from Linköping to Västervik, one of the countryside's most beautiful stretches of rail."
So that would be what, 2.5 cows/mile efficiency? First it's cows..what's next? Rounding up stray dog/cats? Unclaimed human corpses from the morgue? I don't know... it's starting to sound like the basis for a creepy Stephen King novel, crossed with the Polar Express. Let's call it the Corpse Express. Maybe Tom Hanks will agree to narrate?
